Question

Which ordered pair is the best estimate for the solution of the

Answer 1

Answer:

  (a)  (3.5, 1.6)

Step-by-step explanation:

The solution of the system of equations is the point where the lines cross. That point appears to be slightly above the middle of the grid square bounded horizontally by x=3 and x=4, and bounded vertically by y=1 and y=2.

__

The solution ordered pair is (x-coordinate, y-coordinate). We observe that the x-coordinate is approximately 3.5, The y-coordinate is slightly more than 1.5, but not as great as 1.9. So, the approximate solution is ...

  (x, y) ≈ (3.5, 1.6)

_____

The graphing calculator shows the solution is quite close to (3.5, 1.6).
